Give Every Agent an Ephemeral Linux Sandbox — via MCP
Best for Running untrusted code or shell commands safely without exposing host system secrets.
Kilntainers is an MCP server that gives LLM agents isolated Linux sandboxes for executing shell commands.
🧰 Multiple backends: Containers (Docker, Podman), cloud-hosted micro-VMs (Modal, E2B), and WebAssembly sandboxes (WASM BusyBox, or any WASM module). 🏝️ Isolated per agent: Every agent gets its own dedicated sandbox — no shared state, no cross-contamination. 🧹 Ephemeral:…
What it does
- Isolated Linux sandboxes per agent session
- Support for multiple backends including Docker, Podman, and WASM
- Ephemeral lifecycle with automatic cleanup after session termination
- Secure design preventing agent secret exposure to the sandbox
- Scalable architecture for parallel agent execution
